Which sound has waves with the greatest amplitude?

noisy classroom

jet takeoff

loud music

light whisper

Jet takeoff sound has waves with the greatest amplitude.

Option: B.

Step-by-step explanation:

The sound intensity is measured in decibels and sound intensity is directly proportional to Amplitude.

Thus if the decibel increases, then the amplitude will also get increased.

From the given graph we have the respective data

Decibel of Jet Takeoff = 100 dB.

Decibel of Light Whisper = 10 dB.

Decibel of Noisy Classroom = 60 dB.

Decibel of Loud Music = 80 dB.

Thus among these Jet takeoff has the highest decibel amount.

So the amplitude of the Jet Takeoff's Sound wave will be the greatest among other three sound waves.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70
